Configure the proxy settings in the .bashrc
If you want set the proxy for all the users you can do it in the system wide .bashrc file.
sudo vi /etc/bash.bashrc

#proxy settings
export http_proxy=http://DOMAIN\USERNAME:PASSWORD@SERVER:PORT/
export ftp_proxy=http://DOMAIN\USERNAME:PASSWORD@SERVER:PORT/

Additionally if you want APT to use a proxy server you can configure it in the /etc/apt/apt.conf configuration file.

# file.
# Improvements: Add the partial file, a /etc/hosts_dev with some development hosts and creates 
# a logfile

Customizing your shell prompt

Shell prompts are extremely customizable. You can customize them in two ways: (1) by using command characters that print out special things and (2) by using colors.
